Evolving the Revolution

After starting the aero jersey revolution in pro cycling, Castelli have continued to perfect this piece. Version 5.1 builds on the race-leading aerodynamics while making the jersey more comfortable and durable. Updated fabrics on the front and back showed a 2-watt gain in the wind tunnel compared to the previous version. It may not sound much but over the course of a long ride or race that's a significant energy saving.

But it’s not just aero; the Aero race 5.1 is also extremely light, coming in at just 103g. That’s about 40 g lighter than a standard jersey and almost as light as Castelli's own Climber’s Jersey. Just like you, Castelli pro riders are looking for comfort, and the lightweight polyester fabrics in this jersey dry nearly instantly, making this the go-to choice even for cool- or wet- weather racing. The compression band around the pockets keeps them from moving or bouncing no matter how you load them up - perfect for long days in the saddle.

About Short Sleeve Cycling Jerseys

Short sleeve cycling jerseys are cut to provide a close fit whilst riding, they are made from stretchy, breathable materials, which help transfer moisture away from the body and keep you comfortable on the bike. They are best combined with a quality base layer on hot days and can be worn under a jacket on cooler days, making them a good choice as part of a layering system as well as a single item. When choosing a jersey consider how much venting you would like and look at the zip lengths, the longer the zip the higher the ventilation choice you will have. Cycle Jerseys also feature open pockets on the rear for carrying items such as energy gels, energy bars or inner tubes.

Great fit, feels aero and has proved durableBought this jersey ahead of TT season as didn't want to commit to the full skinsuit. Jersey fits great (XL 5'11 175lb) and is really comfortable when on TT bars. Don't want to give the jersey too much credit as did put a bit of training in but times improved all year and I'm sure this played its small part. Took a tumble in last TT of the year landing on shoulder & back. Jersey, and thankfully bike, escaped without a pulled thread. Worn & washed twice a week and still looking good.
Might invest in 3.3 speedsuit for next year.

cool and aeroi've been wearing this a lot for long/hot rides, compared to a typical jersey it's considerably more comfortable once the temperature is into the 30s, i've hardly worn the other jerseys at all as this one is so much cooler to wear
pocket size is normal, unlike the tiny pockets on the climber's jersey!
i'd say it's more delicate than normal, needs a bit of care putting it on and especially when taking off as the arm grip area really hangs on once it's wet
compared to other castelli jerseys, it's snug, but that's to be expected for aero, it's cut to fit in position on the bike, standing it feels 'wrong' around the arms/chest
i take the same size as for a non-aero castelli, fit was ok for me
if you normally take size 'x' in a non-aero castelli, if that's already snug, then go up a size for the aero

Specs

Weight?
Race fit?
Suitable for taller / slim riders?
I'm looking for something super light (riding in Malaysian heat), aero (KOM-chasing) and stretchy so I can get an L which should fit my height (I'm 6'6&quot;) and chest (athletic build). I've been looking for several years now and always end up with either sports bras or flappy sails :/

Asked by: sisarge

The approximate weight of this product is 103g (Large). The mesh design offers a breathable structure ideal for warmer climates.
We'd advise choosing a size based chest and waist measurement.
